Kilojoules per inch to kilojoules per millimeter
Type a value in kJ/in to get it in kJ/mm instantly.
0.04724kJ/mm
Nothing on our list is smaller: thin sheet welding is 6.4× higher. A 200 A, 25 V arc would have to travel about 5,080 mm a minute.
Convert the other way: kJ/mm to kJ/in
What it means
How much heat goes in?
Heat input is arc energy times a process efficiency: about 0.8 for stick and MIG, 0.6 for TIG, and 1.0 for submerged arc.
The math
How to convert kJ/in to kJ/mm
To convert kilojoules per inch to kilojoules per millimeter, multiply by 0.0393701.
Example: 1.2 kJ/in × 0.0393701 = 0.0472441 kJ/mm.
In the other direction, 1 kJ/mm = 25.4 kJ/in.
